SPECIFICATION forming part of Letters Patent No. 281,035, dated July 10, 1883.

Application filed February 17, 1883. (No model.)

To all whom it may concern:

Be it known that we, EDWARD FRAnooIs Dnur'ionaun and J AMES HENRY REYNOLDS, residents of the city of N ew Orleans, parish of Orleans, and State of Loni siana,have invented a certain new and useful Improvement in Me ehanical Fans, and we do hereby declare the following to be a full, clear, and correct description of the same, reference being had to the annexed drawings, making a part of this specification.

The object of our invention is to provide an improved mechanism for operating fans, and in the construction of vibrating fans to secure the positive movement of a rigid leaf and independent movements of flexible pieces, flies, or streamers arranged upon the opposite sides of the said rigid leaf, and raised thereby in so oh manner that the quick. positive movement of the rigid leaf will raise the flies alternately upon opposite sides with a quick positive movement and allow them to fall slowly by their weight alone, as will hereinafter more fully appear.

In the accompanying drawings, Figure 1 is a perspective view of the interior of a room, showing a set of improved fans with mechanism for operating them; Fig. 2, an enlarged elevation of the frame-work and balance-pendulum of afan in detail; Fig. 3, a sectionalview of the pendulum and its operating-bar in the line was of Fig. 2 5 Fig. 4,'a cross-section through the fan-frame in the line y y of Fig. 1, showing one of the flies in contact with the rigid leaf and the other fly falling independently of it; and Fig. 5, a perspective view of a fan provided'with independent streamers in lieu of the flies.

The fan A is formed of a rigid frame of light material, across which isstretched and secured canvas or other suitable fabric. The fan-frame is secured at any desired height to a shaft, B,

motion at either a retarded or an accelerated speed, as may be determined by the position of the ball upon the rod. A reciprocating rod, G, is held in a horizontal position upon the wall by brackets g g, so that it may slide endwise freely, and is connected to the arc G by links or straps h h in opposite directions, so that as the rod reciprocates an oscillating or vibratory motion may be imparted to the pendulum fan-shaft and fans suspended therefrom. One end of the rod G is pivoted to the upper end of a lever, I, which is also pivoted to some fixed frame or wall by a pivot-pin, 7c, and the lower end of the lever I is pivoted to the end of a connecting rod orlink, L, that is operated upon by gearingma, supported upon brackets m a, in such manner that the lever I will be caused to vibrate by the revolution of the gearing and reciprocate the rod G, as shown in Fig. 1 of the drawings. The gearing may be revolved by hand, in which case a crank handle, 0, is secured to the gear-wheel n, or by any well-known motor. A spring or weight may be used to operate the driving-gear, in whichcase the pendulum-arc C may be operated by the reciprocating rod G through any well-known cscapement mechanism.

To the upper cross-bar of the frame of the rigid leaf is secured by battens b and bolts 25 a loose flexible sheet of light material-such as fly-paper or gauze to provide flies bb upon each side of th e rigid leaf-in such manner that the flies may be alternately lifted by the leaf to a considerable elevation, and then allowed to fall by their weight only, until again raised by the second vibration of the leaf. As the flies are made of extremely light material, their descent will be materially retarded by the atmosphere, and they will move much more slowly than the leaf operated at any desired speed by positive mechanism. The flies may be made in separate strips secured to opposite sides of the fan-frame, as shown in Fig. 5 of the drawings, and form streamers that will operate effectively as a fly-fan. The rigidleaf of the fan may be ornamented by painting, embroidery, or otherwise, and will be protected from being soiled by fly-dirt by means of the flies and streamers. The flies, being made of cheap material, may be readily removed and replaced at but little cost when they become soiled and the remaining portion of the apparatus may be a permanent fixture of the room, expensively and elaborately ornamented to form a part of the decorations of the room.

We claim as our invention and desire to secure by Letters Patent 1. In a mechanical fan, the leaf b, the shaft B, the vibrating pendulum c d, provided with an adjustable weight, a, and the reciprocating rod G, for vibrating the pendulum and fan, substantially as described.

2. The combination of the fans, the horizontal rod 13, the are 0; the rod G, and the links or straps h h connecting the rod with opposite sides of the arc, substantially as and for the purpose described.

3. The rigid vibratory leaf 1), shaft B, and flies or streamers b b, secured to the leaf 1) at their upper ends and allowed to vibrate freely and independently of the rigid leaf, in the manner and for the purposesubstantially as described.

In testimony whereof we affix our signatures in presence of two Witnesses.
